If pouring over color swatches at Home Depot leaves you overwhelmed, the Rubitone could make the process easier by helping to assess your options in a form that nerds can understand. Unlike a traditional Rubik's cube, the object here is not to solve it, but to match colors that might look good in a bedroom or living space. The problem is that Rubitone is only a concept, so my walls will just have to stay plain and white for now. [Rubitone via Boing Boing Gadgets]
